Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a T-type pipeline filter. Background Art

[0002] T-type pipe filter is used to filter impurities during the transportation of liquid. It is mainly composed of a tube shell, a filter element, a fixed flange and a flange cover. The flange cover and the fixed flange are fixedly connected by bolts. In order to ensure the permeability of the liquid, the filter element needs to be regularly pulled out for cleaning.

[0003] Since the T-shaped pipe is made of opaque and non-transparent material, it is impossible to directly observe the usage status of the filter cartridge inside it and whether the filter cartridge needs to be cleaned. In order to solve the above-mentioned problems, this document discloses a T-shaped pipe filter. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art that the existing T-shaped pipes are all made of opaque and non-transparent materials, and it is impossible to directly observe the use status of the filter cartridge inside and whether the filter cartridge needs to be cleaned, and proposes a T-shaped pipe filter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A T-type pipe filter, comprising a T-type pipe, and further comprising:

[0007] Flange, fixedly sleeved on the outer wall of the three pipe openings of the T-shaped pipe;

[0008] The flange cover is fixedly connected to any one of the two pipe openings of the T-shaped pipe that are far away from each other by bolts;

[0009] The filter cartridge is installed on one side of the flange cover and located inside the T-tube to filter the liquid;

[0010] The detection component is arranged on one side of the flange cover and is used to detect the use status of the filter cartridge.

[0011] In a possible design, a first groove and an annular groove are provided on one side of the flange cover, a circular plate is threadedly connected to the inner wall of the first groove, a circular body is integrally formed at one end of the filter cartridge, a first circular ring is fixedly sleeved on the outer wall of the circular body, a convex ring is fixedly connected to one side of the first circular ring, and the convex ring is threadedly screwed to the annular groove.

[0012] In a possible design, a second circular ring is fixedly sleeved on the outer wall of the other end of the filter cartridge, and rubber rings are fixedly sleeved on the outer walls of the first circular ring and the second circular ring.

[0013] In a possible design, the detection component includes a second groove fixedly opened on one side of a circular plate, a pressure sensor is fixedly installed on the inner wall of one side of the second groove, two sliding rods are symmetrically fixedly connected to the inner wall of one side of the circular plate, the outer wall sliding sleeves of the two sliding rods are provided with the same contact plate, and the outer wall of the contact plate is sealingly and slidingly fitted with the inner wall of the annular body, a resistance block is fixedly connected to one side of the contact plate, and the resistance block is in resistance with the pressure sensor, a display screen is fixedly installed on the outer wall of the T-tube, and the display screen is electrically connected to the pressure sensor.

[0014] In a possible design, the contact plate is made of rubber.

[0015] In a possible design, the threaded sections of the circular plate and the outer wall of the convex ring are both wrapped with raw tape.

[0016] In the present application, when in use, under normal circumstances, the liquid enters the filter cartridge from the liquid inlet end, is filtered, and then flows out from the liquid outlet end. After the liquid enters the filter cartridge, part of the fluid will impact one side of the contact plate, and the force of the fluid impacting the contact plate will be transmitted to the pressure sensor through the resistance block, thereby detecting the impact force of the fluid. If the filter device filters the fluid for a long time, a large amount of particles and other substances will accumulate inside the filter cartridge, which will gradually form a filter cake in the filter holes on the outer wall of the filter cartridge. The formation of the filter cake will make the filtering effect of the filter cartridge worse. At this time, when the fluid passes through the filter cartridge again, since part of the filter holes on the outer wall of the filter cartridge are blocked by the filter cake, the impact force generated by the fluid on the contact plate will become stronger, making the value detected by the pressure sensor higher. Therefore, we can judge whether the filter cartridge needs to be cleaned by the size of the impact force generated by the fluid on the contact plate.

[0017] If the filter cartridge needs to be cleaned, first loosen and remove the bolts between the flange and the flange cover in turn, take out the flange cover from the inside of the T-tube, then rotate the filter cartridge, release the limit of the convex ring and the annular groove, and separate the filter cartridge from the circular plate. Since the filter cartridge is in a through state, some particles and other materials will fall out from the inside of the filter cartridge when the filter cartridge is separated from the circular plate. Then clean the inner wall of the filter cartridge and one side of the contact plate. In addition, the flange cover and the circular plate can be separated by rotating the contact plate, and any of the components can be replaced.

[0018] In the utility model, the T-type pipe filter can detect the change of the water flow impact force through the detection component to judge whether the filter cartridge needs to be cleaned;

[0019] In the utility model, each component is detachably connected, and if a component is damaged, any one of the components can be replaced. The change in fluid impact force can be used to determine whether the filter holes on the outer wall of the filter cartridge are blocked due to a large number of particulate impurities, thereby determining whether the filter cartridge needs to be cleaned.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Reference Figure 1-Figure 4A filter comprises: a T-tube 1, a flange 2 fixedly sleeved on the outer wall of the three pipe openings of the T-tube 1, a flange cover 3 fixedly connected to any one of the two pipe openings of the T-tube 1 that are far away from each other by bolts, a filter cartridge 4 installed on one side of the flange cover 3 and located inside the T-tube 1 for filtering liquid, a first groove 301 and an annular groove 302 are opened on one side of the flange cover 3, a circular plate 6 is threadedly connected to the inner wall of the first groove 301, a circular body 5 is integrally formed at one end of the filter cartridge 4, and a first circular body 5 is fixedly sleeved on the outer wall of the circular body 5 The circular ring 7, one side of the first circular ring 7 is fixedly connected with a convex ring 701, and the convex ring 701 is threadedly screwed with the annular groove 302. If the device needs to be disassembled, first loosen and remove the bolts between the flange 2 and the flange cover 3 in sequence, take out the flange cover 3 from the inside of the T-tube 1, rotate the filter cartridge 4, release the limit of the convex ring 701 and the annular groove 302, separate the filter cartridge 4 from the circular plate 6, rotate the contact plate 9, separate the flange cover 3 from the circular plate 6, if any one of the components is damaged, it can be replaced, which is convenient for us to replace the components.

[0028] In one aspect of the present embodiment, referring to the figure, the outer wall of the other end of the filter cartridge 4 is fixedly sleeved with a second ring 8, the outer walls of the first ring 7 and the second ring 8 are fixedly sleeved with a rubber ring 13, and the outer wall of the second ring 8 is sleeved with a rubber ring 13. In order to prevent unfiltered water from flowing directly from the outer wall of the second ring 8 and the inner wall of the T-tube 1 to the direction of the liquid outlet, a rubber ring 13 is arranged on the outer wall of the first ring 7 to prevent the fluid in the T-tube 1 from flowing out.

[0029] In one aspect of this embodiment, referring to the figures, the threaded sections of the circular plate 6 and the outer wall of the convex ring 701 are both wrapped with raw tape to enhance the sealing of the pipe connection to prevent liquid leakage.

[0030] The present application can be used in the field of T-type pipe filters, and can also be applied to other fields of the present application.

[0031] Example 2

[0032] refer to Figure 3 , Figure 4, improved on the basis of Example 1: a T-type pipe filter, which is used in the technical field of T-type pipe filters, and also includes a detection component arranged on one side of the flange cover 3, which is used to detect the use status of the filter cartridge 4, the detection component includes a second groove 601 fixedly opened on one side of the circular plate 6, and a pressure sensor 12 is fixedly installed on the inner wall of one side of the second groove 601. The pressure sensor 12 can be the same as that described in the Chinese patent document with announcement number CN111465831A, and the inner wall of one side of the circular plate 6 is symmetrically fixedly connected with two sliding rods 10, and the outer wall sliding sleeves of the two sliding rods 10 are provided with the same contact plate 9, and the outer wall of the contact plate 9 is sealed and slidably fitted with the inner wall of the annular body 5, and a resistance block 11 is fixedly connected to one side of the contact plate 9, and the resistance block 11 is in conflict with the pressure sensor 12, and a display screen 14 is fixedly installed on the outer wall of the T-tube 1, and the display screen 14 is electrically connected to the pressure sensor 12, and when the fluid hits the surface of one side of the contact plate 9, the contact plate 9 is in normal state. 9 will move in the direction of the pressure sensor 12, but because the resistance block 11 is in conflict with the pressure sensor 12, the force of the fluid hitting the contact plate 9 will be transmitted to the pressure sensor 12 through the resistance block 11, thereby detecting the force of the water flow impacting the contact plate 9. When the filter device filters the fluid for a long time, a large amount of particles and other substances will accumulate inside the filter cartridge 4, and a filter cake will gradually form in the filter holes on the outer wall of the filter cartridge 4. The formation of the filter cake will affect the filtration flow rate. At this time, when the fluid passes through the inner wall of the filter cartridge 4 again, since part of the filter holes on the outer wall of the filter cartridge 4 are blocked by the filter cake, the impact force generated by the fluid on the contact plate 9 will become stronger, making the value detected by the pressure sensor 12 higher. At this time, the impact force generated by the fluid on the contact plate 9 can be determined by observing the value on the display screen 14, and then the use status of the filter cartridge 4 can be judged. If the impact force value of the fluid on the contact plate 9 exceeds a certain range, it indicates that a large amount of dust particles and other substances are deposited inside the filter cartridge 4 and it needs to be cleaned.

[0033] In one aspect of this embodiment, referring to Figure 4 The contact plate 9 is made of rubber, which improves the sealing effect and prevents liquid from penetrating into the second groove 601. At the same time, rubber has good elasticity and can more easily transmit the impact force of water flow.

[0034] However, as is well known to those skilled in the art, the working principles and wiring methods of the pressure sensor 12 and the display screen 14 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
